ROLLER-=BEARING- Specification of Letters Patent.

Patented May 28, 1907.

Application fil d December 20, 1906. Serial No. 348,690.

To all whom it 71mg concern.-

Be it known that I, ERNST GEsoHKE, a citizen of the Empire of Germany,residing in Charlottenburg, in the Empire of Germany, have inventedcertain new and useful Improvements in Roller-Bearings, of which thefollowing is a specification.

This invention relates to roller-bearings, and the object of theinvention is to provide such a bearing in which the rollers are mountedand arranged in an improved manner between the relatively movablesurfaces of the bearing.

lVith this end in view, the invention consists in a roller-bearing whichcomprises the novel features of construction and combinations of-part-sto be hereinafter described and claimed.

In the accompanying drawings, in which similar reference charactersindicate corresponding arts throughout the views, Figure 11 is an eevation of a roller-bearing constructed in accordance with theinvention, said bearingbeing shown as partially broken away, Fig. 2' isa section on line 2, 2, Fig. 1, Fig. i is a section through theroller-carrying cage, Fig. 4 shows in section a modified arrangement ofthe bearing, and Fig. 5 is a detail showing the manner in which thedistance-pieces are secured between the siderings of the cage.

In the drawings u denotesan inner rin and c an outer ring, one of whichis intende to be stationary and the other rotatable. These rings areconcentric with each other and lie in the same plane, as shown in Fi 2.They are provided upon their outer e ges with recesses in which are setannular plates or rings a by which said rings are spaced apart at auniform distance throughout their circumferences. The annular plates 0are connected at equidistantly spaced points by means of pins 0, theouter ends of which are upset, as shown in Fig. 2,

cage which is interposed between the bearing-rmgs.

Mounted upon, the pins 0 of the cage are rollers w which rotate incontact with the. opposing surfaces of the bearing-rings. In the spacebetween each two adjacent rollers w whereby the rings a form inconpinction with said pins a there are arranged a number rollers thereare arranged distance-pieces sin the form of radially-arranged plateswhich permit the rollers r to have a certain play, but do not contactwith the rollers 10. Said distance-pieces are secured between the annular plates a by the ends of said distance-pieces and engagingc0rrespondin recesses in the inner surfaces of said annul ar plates, asshown in Fig. 5. When the cage is formed the distance-pieces areinterposed between the annular sideplates and said plates are thenconnected by the pins 0 as before described, In addition to theirfunction of separating the rollers of the bearing, the distance-pieces 8cause the annular side-plates to be spaced apart uniformly throughouttheir circumferences and impart great rigidity to the ball-carryingcage.

The side-plates a rotate freely in the corresponding grooves of thebearing-rings and by such engagement with the grooves the lateralmovement of said plates and the rollers is prevented. By the arrangementof the side-plates a the access of dust and the like to the rollers andbearing surfaces is prevented.

As before stated, the rollers w do not contact with the distance-piecesand the friction between said distance-pieces and the free rollers risvery slight.

In the form shown inFig. 4, antifrictionballs are interposed between theopposing surfaces of the side-plates a and of the bearing-rings u, o. Insaid figure p denotes the balls which are interposed between the ring aand the plates (1, and g those which are interpo'sed between said platesand the outer caring-ring '1). This construction is used where thebearing is subjected to greater strain than that for which thefirst-described form is adapted.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
